# run-duplicate-gate

`station__microgram__run-duplicate-gate` · external (needs EXECUTION_BACKEND_URL configured) · domain `microgram` · pv-relevance `pv-core`

Duplicate case detection: classifies case pairs as CONFIRMED/PROBABLE/POSSIBLE/UNLIKELY duplicate based on matching criteria and time window

> **Note:** This tool routes through an external execution backend. If `EXECUTION_BACKEND_URL` is unset on the server, calls return JSON-RPC error `-32603 "Tool execution backend not configured"`. Tools with `backend: native` execute in-process and are always callable.
